[TenTec] best power supply for Orion II and other items

[Richards]

Gentlemen -

1)  How I know if RF from my Omni VII was causing problems with my 
Astron RS-35M linear type power supply ?  Would it show up as an 
anomalous readout on one or both meters?   What if I had the model 
without any meters - how would one tell ?

2)  Could RF be getting into it from other gear not even powered by it - 
say, by a 2 meter mobile used in the shack as a base rig for local 
repeater work?

3)  How could one tell if a "current"  (pun intended)  Model RX-35M is 
grounded as described ?   Is there an easy to identify spot on the power 
supply's schematic diagram ?  (I am a rookie at this, but might be able 
to trace it with some local assistance or description here...)  Or would 
one just contact Astron and ask ?  (...which is easy enough, but I am 
trying to learn to use what info is already at hand...)

Thanks in advance.

the Astron supply is good but if the negative

energy gets into the regulator circuitry...
